Ice & ice-movement

Over the past 40 years, ice cores have revealed more about climate change than any other scientific technique. Over the last few decades, satellites have detected changes to the amount of sea ice that covers the polar oceans. Since 1979 summer sea-ice extent in the Arctic has reduced at 10% per decade. Some major glaciers that drain the Antarctic and Greenland ice sheets have accelerated by as much as 50%.

DATA AS ART #09

Volcanic ash Ice cores are cylinders of ice (approximately 10cm wide) drilled out of an ice sheet or glacier. On the East Antarctic Ice Sheet, these can be up to …

Bedmap Himalayas

Bedmap Himalayas is an ongoing BAS core-funded and grant-funded programme. It aims to measure how much water much is stored as glacier ice in High Mountain Asia. In warm weather, …

Weddell Sea ice sheet and climate

In the south of the Weddell Sea lies the Ronne and Filchner Ice Shelves. During the coldest part of the last glacial period about 25,000 years ago, the ice in …

Ocean-driven ice-shelf thinning in Antarctica

By exploiting advances in ice sheet modelling, and new Antarctic-wide datasets, this project aims to predict how far and how fast the observed ocean-driven thinning of floating ice shelves will …

Ice Sheet Modelling

The research of the ice sheet modelling group focuses on integrating observational data with dynamical models that describe how the ice flows in order to improve our representation of how …

Antarctic Climate over the last millennia

The Antarctic Peninsula and West Antarctica have warmed dramatically in recent decades, with some climate records indicating that these are among the most rapidly warming regions on Earth. The Antarctic …

Climate and Ice during the Last Interglacial

During the Last Interglacial (129-116 thousand years ago, ka) CO2 and global temperature were both higher than they were before human industrialisation. By examining Last Interglacial climate, we thus gain …

West Antarctica wind strength and atmospheric circulation

Changes in wind strength and circulation patterns above the Antarctic Peninsula are linked to its warming and increased upwelling of warm circumpolar deep water, resulting in accelerated melting and thinning …

Arctic marine geophysics

This research focuses on investigating the glacial histories of Arctic ice sheets and ice caps using the marine geological record preserved on continental margins. By reconstructing past ice sheets, their …

Depositional patterns and records in sediment drifts off the Antarctic Peninsula and West Antarctica

The biggest uncertainty in predictions of sea-level rise is what the contribution will be from the great ice sheets on Antarctica and Greenland as climate warms. The West Antarctic Ice …

Antarctic tipping points

1 June, 2023

Concern is rising about tipping points in the Antarctic region (Armstrong et al., 2022). Recent heatwaves, changes in the Southern Ocean, and a reduction in the extent of Antarctic sea …
